No, the two are not the same.

The audio output transformer is mounted on the speaker frame. Hang on...

(goes downstairs to retrieve notebook of Philco schematics)

(returns and looks inside)

You should be reading around 700 ohms between each plate of the two 6F6G tubes with the speaker connected to the radio. If not (and I suspect you will see infinite resistance, based on your earlier comments), one half of that audio output transformer is bad.
